The 19-year-old Swedish singer started the song on her own dressed in a black tube top and matching pants, and navigated the stage like a veteran. Then, at about two minutes mark, Ty joined in, wearing a black overcoat, a black-and-white striped shirt and shades, and complimented Larsson’s melodic vocals with half-sung raps.

Larsson’s new album So Good comes out March 17th and includes the singles “Lush Life, “Ain’t My Fault” and the MNEK collaboration “Never Forget You.”
